Research topics
Quantum entanglement and dynamics in constrained many-electron systems
I will conduct research on (i) magnetism in ferromagnetic t-J models and (ii) constrained dynamics of hard-core particle systems with a particular emphasis on constraints arising from electron correlation. For the first topic, as an intermediate step towards the understanding of why metals such as iron exhibit ferromagnetism, which is a long-standing problem in condensed matter physics, we study the ground-state properties of the ferromagnetic t-J model and clarify its magnetism. For the second topic, motivated by recent experiments on Rydberg atom arrays, we investigate their anomalous dynamics theoretically. In particular, we aim to show analytically the non-ergodic behavior of physical quantities observed in experiments and examine whether such behavior can be found in two and higher dimensions.


I am very honored to receive the Inamori Research Grant. My research topic is challenging, as it has not been studied much in Japan and is different from what I have been working on. I will, however, do my best to make significant progress in this field.
